Conclusion: Pass A.2.2. Average Output Power-conducted Method of Measurement: See ANSI C63.10-2013-clause 11.9.2.2.2 The procedure for this method is as follows: a) Set span = 1.5OBW. b) Set RBW = 1MHz. c) Set VBW = 3MHz d) Number of points in sweep = 625 e) Sweep time = auto. f) Detector = RMS. g) If transmit duty cycle < 98%, use a sweep trigger with the level set to enable triggering only on full power pulses. The transmitter shall operate at the maximum power control level for the entire duration of every sweep. If the EUT transmits continuously (i.e., with no OFFintervals) or at duty cycle ≥98%, and if each transmission is entirely at the maximum power control level, then the trigger shall be set to “free run.” h) Trace average 100 traces in power averaging (rms) mode. i) Compute power by integrating the spectrum across the OBW of the signal using the instrument’s band power measurement function, with band limits set equal to the OBW band edges. If the instrument does not have a band power function, sum the spectrum levels (in power units) at intervals equal to the RBW extending across the entire OBW of the spectrum.
